Physician, Assistant Professor
Urology
Department: Urology
I am a urologist at The Ohio State University Wexner Medical Center and serve as the medical director of the Urology Clinic at the Eye and Ear Institute. As a general urologist, I diagnose and treat patients with a variety of conditions. I specialize in treating men with voiding dysfunction disorders such as benign prostatic hyperplasia, overactive bladder, prostatitis and pelvic floor dysfunction, and I perform vasectomy procedures.
I am passionate about improving my patients’ lives and enhancing the quality of care. I strive to provide personalized care for every patient, and I work with them to create customized treatment plans based on their goals and priorities.
My research experience began as a cancer epidemiologist at the American Cancer Society. During that time, I developed a strong interest in identifying and addressing factors that contribute to cancer incidence and mortality, including tobacco use and racial disparities. This population-centric view in epidemiology inspired me to pursue a career as a clinician, where I could interact with patients and impact patient care and outcomes on an individual level. My current research work is focused on patient satisfaction, physician and hospital quality ratings, and the impact of smoking on surgical complications. My work has been featured in peer-reviewed publications such as the Journal of the American Medical Association (JAMA), Journal of Urology, and Journal of the National Cancer Institute (JNCI).
When I’m not working, I love spending time with my family and playing golf. I also enjoy woodworking and traveling.
Please note: Not all physicians schedule patients at each listed location.
My research experience began when I worked as a cancer epidemiologist at the American Cancer Society after training in epidemiology at the Emory University Rollins School of Public Health. During that time, I gained a personal interest in identifying and addressing factors that contribute to cancer incidence and mortality, including tobacco use and racial disparities. This population-centric view in epidemiology then led me to pursue a career as a clinician, where I could interact with patients and impact patient care and outcomes on an individual level.
Following medical school at the University of Michigan, I completed my urology residency at Northwestern University. During this residency, I completed a research fellowship in the Surgical Outcomes and Quality Improvement Center and focused my research on patient satisfaction, physician and hospital quality ratings and the impact of smoking on surgical complications.
As a urologist, my work has focused on identifying measures and interventions to improve the quality of care that we provide patients with both benign and malignant urologic conditions, especially those undergoing surgical procedures. I am also interested in measurement of hospital and physician quality in the form of publicly reported hospital and physician ratings. I believe it is important to understand both the strengths and limitations of these systems to better inform the patients who use these rating systems to guide where they seek care.
I appreciate the commitment to innovation here in The Ohio State University College of Medicine, and the readily available resources that allow me to pursue highly complex research.
The overall patient satisfaction rating is an average of all patient responses to the six doctor communication related questions shown below from the Clinician and Group Consumer Assessment of Healthcare Providers and Systems survey. For additional information about the patient satisfaction survey, please visit our Patient Satisfaction Survey page.

At The Ohio State University Wexner Medical Center, we support a faculty member’s research and consulting in collaboration with medical device, research and/or drug companies because a faculty member’s expertise can guide important advancements in the practice of medicine and improve patient care. In order to provide effective management of these relationships, the University requires annual disclosures from all faculty members with external interests related to their University responsibilities.

Dr.Delancey was very knowledgeable about my medical problem. He was also very nice and listened to me. The doctor spent a lot of time with me discussing my situation.

Dr was responsive, prepared and open to my questions
Good doc, I'm sure, but I'd have liked a little more of the "what this could be" discussion.
The care provider was able to tell me exactly what my issue was and various solutions/treatments currently available, and what he felt the ideal treatment would be.
